MFD: TPS65910: Add new mfd device for TPS65910
The TPS65910 chip is a power management IC for multimedia and handheld
devices. It contains the following components:
- Regulators
- GPIO controller
- RTC
The tps65910 core driver is registered as a platform driver and provides
communication through I2C with the host device for the different
components.

regulator: Support voltage offsets to compensate for drops in system
Some systems, particularly physically large systems used for early
prototyping, may experience substantial voltage drops between the regulator
and the consumers as a result of long traces in the system. With these
systems voltages may need to be set higher than requested in order to
ensure reliable system operation.
Allow systems to work around such hardware issues by allowing constraints
to supply an offset to be applied to any requested and reported voltages.
This is not ideal, especially since the voltage drop may be load dependant,
but is sufficient for most affected systems, it is not expected to be used
in production hardware. The offset is applied after all constraint
processing so constraints should be specified in terms of consumer values
not physically configured values.

This actually fixes an off-by-one bug while accessing mc13892_regulators array.
